Insurance that covers the lender against some of the losses incurred as a result of a default on a home loan. Often mistakenly referred to as PMI, which is actually the name of one of the larger mortgage insurers. Mortgage insurance is usually required in one form or another on all loans that have a loan-to-value higher than eighty percent. Mortgages above 80% LTV that call themselves “No MI” are usually a made at a higher interest rate. Instead of the borrower paying the mortgage insurance premiums directly, they pay a higher interest rate to the lender, which then pays the mortgage insurance themselves. Also, FHA loans and certain first-time homebuyer programs require mortgage insurance regardless of the loan-to-value.
